The 70-year-old owner of a school in San Diego that helps real estate professionals seeking to obtain or renew their salesperson and broker licenses has been charged with child sex trafficking.

Michael Lustig, the owner of Real Estate License Services Inc., was reportedly picked up in June during a prostitution sting at a motel. Investigators discovered evidence that Lustig exchanged phone calls and text messages with two girls, ages 12 and 13, who said he paid them for sexual encounters.
